 For longer content, you can add a `.text-truncate` class to truncate the text with an ellipsis. **Requires `display: inline-block` or `display: block`.**

 - Reset default horizontal `padding-left` on `<ul>` and `<ol>` elements from browser default `40px` to `2rem`.
 - Simplified table styles (no more 2px border on `thead > th` elements) and tightened cell padding.
 - Dropped `.pre-scrollable` class. [See #29135](https://github.com/twbs/bootstrap/pull/29135)
+- `.text-*` utilities do not add hover and focus states to links anymore. `.link-*` helper classes can be used instead. [See #29267](https://github.com/twbs/bootstrap/pull/29267)

 ## Background color
 
 Similar to the contextual text color classes, easily set the background of an element to any contextual class. Background utilities **do not set `color`**, so in some cases you'll want to use `.text-*` utilities.
